Abdominal pain is a general term for every painful feeling and unpleasant symptoms that
children feel in the abdominal area. This is the most common symptom for children's age to
seek the doctor's office. There are numerous causes that can cause the pain in the abdomen, so
to give the correct and accurate interpretation of this symptom is a great challenge for every
doctor. Sometimes even in the favorable circumstances, with usage of every diagnostic tool
and with the largest clinical skill the cause of pain cannot be detected. Additional problem is
inability of pain defining and its severity, beacuse every person reacts and experience the pain
differently. The children can hardly show where they feel the pain. Despite the decades of
clinical observations, that resulted in many articles , books , and monographs about abdominal
pain in childhood, this problem still remains one of the major concerns for the most pediatric
health workers. The main goal of this research was: to analyze the frequency of clinical
symptoms of abdominal pain in children's age in the prehospitalization, to correlate symptoms
or a group of symptoms in children with abdominal pain in the prehospital setting compared
to the final diagnosis and examine the prediction of clinical symptoms outcome of abdominal
pain in children. In the investigated period of time in emergency care facility Lukavac there
were 36,614 patients examined in total, of which 6666 ( 18.20 % ) were children. Out off
6666 children, that were taken care of, during the investigated period of time in the
Emergency Department in Lukavac, 3689 were males and 2977 were females, with the ratio
of M/F 1.2/1. Abdominal pain had 222 ( 3.3% ) children of the ages of 0-15 years. Out of the
121 children with abdominal age who entered the study protocol 67 (55.37 %) were male and
54 (44.63 %) female. The frequency of the abdominal pain was higher in male children
compared to female children with the ratio M/F 1,2/1, but with no statistically significant
differences (67 vs 54; p=0,122) and with the even chance of the abdominal pain ccurances.
The most common sypmtom was described as abdominal pain which described 74 (61,15%)
of the examined children, and the least represented symptoms were dyspepsia and undefined
jaundice which were present in only 3 (2,47%) children. The symptoms described only as
abdominal pain significantly varied in relation to all the other symptoms (χ²=12,049;
p=0.0005). This symptom had 2.4 times greater chance of occurrence in relation to all the
other symptoms [OR=2,478; 95% CI (11,173 – 4,157)]. Significant incidence of heartburn
that described 14 (11.57 %) of respondents is statistically significant symptom that points to
the seriousness of the problem in relation to all the other symptoms (χ²=139,9; p=0,0001), but
without significant chance that refers specifically to abdominal pain , which may be
associated with other diseases of children [OR=0,017; 95% CI (0,007 – 0,037)].
We also examined the association of laboratory parameters with the final diagnosis and
disease severity in children with abdominal pain. In the study period, 121 children with the
abdominal pain were sent to the Clinical Center of Tuzla and final diagnosis were encrypted
according to the current International Classification. The cause of abdominal pain in 39
children was the appendicitis; diarrhea and gastroenteritis were in 28 children, inguinal hernia
in 20 children, paralytic ileus was in 2 children and peritonitis in only one child. Unmarked
renal colic was recorded in one child, a.cistitis with 13 children, while the abdominal and
pelvic pain was associated with 14 children and unmarked jaundice with 2 boys and a girl.
The authors conclude that the validity of the outcome of clinical symptoms of abdominal pain
in children, the likelihood ratio of positive and negative results, had a positive predictive
value of the test of 73 %, negative predictive value 71 %, with a specificity of 83 % and
sensitivity of 16. The diagnostic value of the test is 73 % .
